To all whom 'it may concern:

Bc it known that I, Francis E. Venous;

scribed and particularlyr pointed out in the claims, vthe invention not boing coniiied'gto precisely the details of construction shown.`

In the accompanying drawings-Figure 1 'ne .with

arts in section; iff 2Vis an elevation lookv#ing at the iiy-wliee'end with parts section; Fig. 3 is a side view of the governor taken from the plane :c-or Fig. 2; Fig. 4 is a detail Villustrating the means for oontrolling the operation of thesparlrer-operat'- in lever; Fi 5 is an elevation of the cyli inc er end ano sparker-operating devices aptions of the crank shaft are purtenant thereto; the sparker with parts in section; Fig. 7 is a view of the left-hand side of what is shown in Fig. 6 showing the sparking oints; Fig. 8 isa section on the line y-y ookin to the right, Fig. 6; Fig. 49 is a plan view o the .-irliaust valve and sparlrer-oper ating lever. v

In the views designates the cylinderhavinin its head `1e lebsupply port 10 furnis ed with a telve 11 controlled by a weak spring 12 tending to close the port, and

an exhaust' port 13 furnished with a valve 14 controlle by a stronger spring 15 tending to close said ort 18. l u

16 designates t e crank shaft having the crank 10* connected with an ordinary piston in the c linder bv means of the rod 17. The crank s iaft has xed to it a pinion 18 meshin with the gear wheel 19 of the governor. T iecircumference ofthe pinion 18 is ha that'. o the gear 19, or so that two revoluuired to etect one rotation of the gear 19'. e gear wheel 19. has ivoted in projections from it governor balls 20 the free ends of which 'the lairis of the shaft 19* of the have invented a certain v ,The inner end of the the angularity lof to the position of the 'engine as` Fig. 6 is a side view ofV l trip ,iectedV atch 32 is hin lscrew 37 isv employed to adjust the are held toward each other b arsprin 21 and the pivoted ends of whic Ahave a ined` theretp arlns2'2 that engage the outer end of a sliding pin v23 that extends eeoentrically vernor. in 23 projects` also through a-cam member secured to the end fhe shaft of the governor. When the enne is running at high speed tliepin 23 is moved outward by centrifugal notion on r the 'governor balls, and conversely, when the engine slows down the pin is thrown inward to permit the closinor of the exhaust ort and the recharging of iecylinder with explo sive gas, as hereinafterexplained.

Fn crumed at 25 below the cylinder 9 is Va ioni lever 26 inode up of two parts hinged toget er at 27, one part being provided with a set `screw 28' to engage the other to lvary the parts to each other. Referring viewedy in Fig. 1, the right-hand end of the lever 26 reaches to plsition to engage the exhaust-port stein an to properly snpiort a rod 29 for operating the sparker, while the left-hand end of said lever is upwardly bent, as seen at 26, `and carries a roller 30 located under the com member 24 and so asto beoperated thereby.v In oonnection with the lever '26 is a spi ing 31 that tends toliold the roller 30 up toward the cam member 24 Vand the lever is oscillated bythe rotations of said cam member. en the speed of the engine is accelerated the lever is held down out of position to be operatecl b the cam device by` means of a lat 32 having a finger 82n that lies in Vthe lpath of thopin 23 onlylwhen prothe slowing speed of the engine dre to e omission of gas cha es and exlosions; as hereinafter explain i The tri l) ly and slidingly monnte on a-shaft 33Y tweenthe arms ofa yoke 34. It is pressed against one arm of oke by a spring rsecured to it and having its other end secured' .to a small collar 3 The spring 35 also holds tlieupper end of the trip latch toward the arm 26. set position of the `yoke so as to regulate the extent of projectionof the pin 23 necessary to o ate the trip latch andtherefore so regir ate the speed of-,the engine. Forl example, if the trip latch be moved tn the-left Fig. 2, the mean speed of the engine will be made means'at one end of `said lever for holding it. in position to retain said valve 1n open position, a governor mechanism, a member operated by said overnor mechanism to release said lever to cg'lose the valve when the speed of the engine is reduced to n degree below its intended mean, a sparking device and means adjustable independently of the lever at the other end of said lever for operating said sparking device.

4. In an explosive gas engine, the combination with the exhaustport and valve therefor, of a. lever for operating the valve to open said port, a trip latch 32 for holding said lever 1n position to retain said valve in open position, a overnor mechanism, a pin operated by sai overnor mechanismyt/o release said trip late 1 to permit the valve to close when the speed of the engine is reduced to a de e below its. intended mean, and means \v ereb)- said trip latch can be shifted Ylever for operatin? the valve to o toward or from a given path of the operati'e end of said pin.

5..In an explosive gas engine, the combination with the exhaust port valve, of a n the port,a trip latch r holding said ever in position to retain the valve in open position, a governor mechanism, varried on e shaft. and driven by the engine, a sliding pin operated by said governor' mechanism to release said lever to close the valve when the speed of thev enfrine is reduced to a de ee below its intended mean, a sparking evice also operated by said lever, and a cam device on the shaft of the governor mechanism to act-uate said lever.
